  1. 16. Estimation and optimal designs for multi-response Emax models

    Författare :Bergrún Tinna Magnúsdóttir; Hans Nyquist; Ziad Taib; Nancy Flournoy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multi-response Emax models; Clinical Utility Index CUI ; optimal designs; system estimation; dose-response studies.; Statistics; statistik;

    Sammanfattning : This thesis concerns optimal designs and estimation approaches for a class of nonlinear dose response models, namely multi-response Emax models. These models describe the relationship between the dose of a drug and two or more efficacy and/or safety variables. LÄS MER

  3. 17. The Non-Linear Instantaneous Least Squares Approach to Signal Parameter Estimation

    Författare :Jakob Ängeby; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aliasing; polynomial-phase signals; synthetic aperture radar auto-focusing; non-linear least squares; time-frequency estimation; estimation theory; non-stationary processes; non-uniform sampling;

    Sammanfattning : Estimation of parameters of non-stationary signals observed in noise is a challenging and difficult task, motivated by applications such as radar and mobile tele-communication. Here, a novel method for signal parameter estimation named the Non-linear Instantaneous Least Squares (NILS) approach is presented, which can be applied to linear and non-linear signals, and to both uniformly and non-uniformly sampled data.

  4. 18. Contributions to Small Area Estimation : Using Random Effects Growth Curve Model

    Författare :Innocent Ngaruye; Martin Singull; Dietrich von Rosen; Tapio Nummi; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This dissertation considers Small Area Estimation with a main focus on estimation and prediction for repeated measures data. The demand of small area statistics is for both cross-sectional and repeated measures data. LÄS MER

  5. 19. Nonparametric Statistical Inference for Entropy-type Functionals

    Författare :David Källberg; Oleg Seleznjev; Timo Koski; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; entropy estimation; Rényi entropy; divergence estimation; quadratic density functional; U-statistics; consistency; asymptotic normality; Poisson convergence; stationary m-dependent sequence; inter-point distances; entropy maximizing distribution; two-sample problem; approximate matching; Mathematical Statistics; matematisk statistik;

    Sammanfattning : In this thesis, we study statistical inference for entropy, divergence, and related functionals of one or two probability distributions. Asymptotic properties of particular nonparametric estimators of such functionals are investigated. We consider estimation from both independent and dependent observations. LÄS MER

  7. 20. Modeling and Sampling of Spectrally Structured Signals

    Författare :Filip Elvander; Statistical Signal Processing Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectral estimation; parameter estimation; optimal mass transport; covariance interpolation; misspecified models; inharmonicity;

    Sammanfattning : This thesis consists of five papers concerned with the modeling of stochastic signals, as well as deterministic signals in stochastic noise, exhibiting different kinds of structure. This structure is manifested as the existence of finite-dimensional parameterizations, and/or in the geometry of the signals' spectral representations. LÄS MER
